The ecological role of detritivores in nutrient cycling is crucial as they break down organic matter, such as dead plants and animals, into simpler compounds. This process facilitates the decomposition of waste materials, returning essential nutrients to the soil and making them available for producers, like plants. Detritivores, which include organisms like earthworms and fungi, enhance soil fertility and promote the overall productivity of ecosystems. Their activity fosters a healthy nutrient cycle, critical for sustaining life.
